How do I find my server utilization in AIX?
You should check out the man pages for sar, vmstat, lsps, ps and topas. You can also download nmon free, which is probably one of the easiest tools to use. This will output the statistics of CPU usage in terms of %user, %sys and %idle percents. This will check your memory (real and virtual).
How do I check CPU and memory in AIX?
AIX Custom Monitoring for CPU, Memory and Disk – Perl Script
- CPU Usage. Command: lparstat. Output: Total CPU, Free CPU, Used CPU, CPU Usage Ratio.
- Computational Memory Usage: Command: vmstat -v.
- Disk Space Usage: Command: df -g.
- Paging Activity: Command: vmstat -w.
What is server CPU utilization?
In other words, the CPU is being used to execute the process. CPU usage is the percentage of time that the CPU is being used to complete its tasks. When your system is up and running, a CPU can be in three states: idle, busy, or waiting for I/O.

What is load average in AIX?
load average is the “r” column under vmstat. This is the number of kernel threads (the runnable threads) It has to be compared to tha actual number of CPUs (logical CPU) if the CPUs can service those threads.
What is the top command in AIX?
Top is part of a package called “monitor” on AIX 5.3. There is no top on AIX systems. Use topas which is close to top on Linux or other Unix systems or look for nmon on IBM site which is very good free utility for monitoring AIX system.
How do I find my server utilization on Linux?
How to Check CPU Utilization in Linux with Command Line
- top Command to View Linux CPU Load.
- mpstat Command to Display CPU Activity.
- sar Command to Show CPU Utilization.
- iostat Command for Average Usage.
How do I check memory on AIX?
On AIX you can use a combination of the commands lsdev and lsattr to determine how much memory the computer has. These commands (located in /usr/sbin) are used to display the system devices and their attributes.
What is CPU utilization vs CPU usage?
utilization – Provides statistics for physical CPUs. cpu. usage – Provides statistics for logical CPUs. This is based on CPU Hyperthreading.
How do you top on AIX?
How do I check CPU utilization in Aix?
Despite it’s a very good idea for your learning path to use the AIX/UNIX commands in order to get the performance behavior, it’s also wise to use the tools people are writing to help you so. Just type one command sar -u 1 10 for check utilization. The first line is an historical since system reboot so ignore it… use the last two lines…
How to get top 10 processes with highest%CPU in Aix?
Answer : ps command can be used to report a snapshot of the current processes in AIX. Use option aux and sort based on the column to get the top usage based on the parameter you need. If you need to get CPU then you will need to sort column 3. Note : Above command will output top 10 processes with highest %CPU in an interval of 2 seconds.
